Abstract: A method includes receiving a source shape that is to be blended with a destination shape stored in a color buffer for an image; in response to determining that the source shape is associated with a blending mode that requires updates to pixels in the color buffer uncovered by the source shape: identifying empty tiles in the color buffer uncovered by the source shape and non-empty tiles in the color buffer covered by the source shape; for each of the empty tiles, sending instructions to clear pixel values associated with the empty tile in the color buffer; and for each of the non-empty tiles: identifying pixels of the non-empty tile that are covered by the destination shape but not the source shape; and sending instructions to clear pixel values associated with the pixels.
